3MM CS X 195MM ID BLACK BUNA 90D

APG stocks the H90M3X195, a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 195 mm (7.677 in), a cross section of 3 mm (0.118 in), and an outside diameter of 201 mm (7.91 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists water, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across general industrial maintenance, hydraulic and pneumatic systems, and construction equipment.

This item is sold individually under part number H90M3X195. Unit weight is approximately 5.553 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
